To ZZZ whom t may concern.' Be it known that we, OTTO LAUBER, residing at Bredeney, Germany, and FRIEDRICH STOCK, residing at Essen-on-the-Ruhr, Germany, both subjects of the Emperor of Germany, have invented a certain new and useful Improvement in Spade-Fastenings for Theeled Gun-Carriages, of which the vfollowing is aspecification. VThis invention relates tospade-fastenings for wheeled gun-carriages, particularly for wheeled carriages of heavy ordnance, and particularly to such a spade-fastening that makes it possible to use a spade, intended for soft ground, and wherein the spade has such large dimensions that when transporting the gun, the spade must be removed from the trail.

`The object of this invention is to allow that the spade on the one hand may easily and quickly be attached to or removed from the tra-il and on the other hand need not be lifted out of the ground when the gun is trained.

In the accompanying drawing is shown one embodiment of the application by way of example.

In the different views ShOWm-Figure l illustrates the trail of a. wheeled gun-carriage partly in` side view, 4with the spade in longitudinal section. `Fig. 2 is a plan view of Fig. l partly in section. Fig. 3 shows separately the trail as employed in Fig. 1. Fig. 4L discloses separately the spade shown in Fig. l. Fig. 5 is a detail in side-view. Fig. 6 is the'left end view of said detail.

The trail consists of two E-shaped side walls A connected by means of a shoe B inclosing their ends, and a cross bar C disposed adjacent said shoe.

The spade D, D1 consists principally of the spade-shaped blade D and the pressplate D1. The spade-blade D and the pressplate D1 are held together by strengthening ribs Z2. On the press-plate D1 is situated a narrow flange d3, the function of which is to engage with the horizontal rib or flange c1 of the cross bar G. The press-plate D1 is provided with a wide flange Z4 against which the rear face b4 of the shoe B is resting when the spade D, D1 is connected with the trail. Besides the flanges Z2 Z1L and theV cross bar C, there are also two clutches or Specification of Letters Patent.

Patented Nov. 25, `1913.

clamps E (see Figs. 5 and 6) servino` as connections between the spade and the trail. Each of these clamps may be set between a pair of lugs b1, situated on the shoe B, and

be secured to their respective pair of lugs i by means of key-bolts F. The clamps E have hooks c1 designed for engagement with the flange Z1 and a surface e2 resting on the surface b2 of the shoe B, when said clamps rack. This pinion is mounted with its pivot g1 in the socket Z5 on the spades press-plate D1. The pinion G has a head piece g2 provided with openings g3 for a hand lever H.

The edge c1 of the cross bar C, the rack b3, the front face b4 of the shoe B and the flange Z4 are all curved concentrically around one center situated equidistant from each wheel on a line connecting their resting .'point-s on the ground.

To attach the spade to the trail one may proceed in the following manner: When the spade has been buried in the ground, the trail is brought to rest on the press-plate D1 ofthe spade in such a way that the horizontal leg of the cross bar G lies directlyin front of the outermost edge of the flange Z3. Then the trail is moved so far rearward on the press-plate D1, that the rear face b4 of the shoe B rests against the flange Zt By this means the cross bar G engages with the flange Z3 vand the tooth-rack 53 enters into mesh with the pinion G. Lastly the clamps E are inserted between the lugs b1 and locked by the key-bolts F. The spade is then so attached to the trail that it is unable to detach itself therefrom, and that the shocks from ring the gun are transferred to the spade. When it is desired to train the carriage the trail is shifted` on the pressplate D1 of the spade by turning the pinion G with the hand-lever I-I. Then the cross bar C will slide along the flange Z3 and the shoe B along the flange Zt How the spade D D1 is removed from the trail needs, after the foregoing,no explanation.

What is claimed is 1. The combination with a wheeled guncarriage having a trail and a spade, ofmeans for easily detaching or attaching said spade to the trail-end, constructed to permit a horizontal displacement between trail-end and spade, said-spade being provided with Xed connecting members and a movable gearing member and said trail provided with ic iXed connecting members and a gearing member, said several members adapted to be brought into engagement with the rethe spade to the trail-end.

3. The combination with a wheeled guncarriage having a trail and a spade, of means for easily detaching said spade from7 or attaching it to the trail-end, gearing eompris- 1 lng rack and pinion for producing lateral displacement between trail-end and i spade, said spade and trail being each provided with two connecting members comprising by running the trail rearward on the spade.

Yt. The combination with a wheeled guncari'iage having a trail and a spade, of means for detachably mounting said spade on the trail-end; said means comprising transverse jaws or flanges on the spade and opposing transverse ianges on the trail-end, and clutches bolted to the trail; and the spade being provided with a pinion and the trail with a rack forming a gear for effecting lateral displacement of the trail on the spade; said gear being brought into mesh and said flanges being brought into engagement si multaneously by running the trail rearward on the spade, substantially as described.

The foregoing specification signed at Bai'- men, Germany, this 23rd day of July, 1910.
